In various machinery and equipment, buy a ball screw ball screw shall note the following: (1) Ball is a precision ball screw transmission price must be lubricated. Within the recommended potassium soap grease nut and No. 1-3 turbine oil lubrication. (2) Like Rolling Ball and Ball, mixed with dust and foreign matter, will reduce the service life. Therefore, we must adopt screw protective cover to protect them. At home and abroad have been equipped with all kinds of ball screw most of the labyrinth ring to prevent dirt from entering the ball screw body. In addition, scrap metal screw easily dipped places, we should also consider using screw protective cover a total length of fencing on the screw. Ball Ball High reliability compared with other transmission machinery, hydraulic, ball screw drive system failure rate is very low, maintenance is also relatively simple, just for general lubrication and dust. It can be operated without lubrication on special occasions. Ball preload applied to the ball screw preload to eliminate axial clearance of the ball screw effect, and further that the amount of deformation generated axial load is minimized, making high-precision positioning means applying a pre-general.
